After learning about variables and their data types, lets use them with operators, and see how many types of operators are there in C sharp in this tutorial

Operators are the part of an expression in c sharp. Expressions are usually formed using operands and the operation that have to be performed on them using operators. Operator may be a keyword or a special symbol defining some operation. operators may work on 1 or more than 1 operands, depending on the operation to be performed.

Operators can be categorized into many groups, depending on their operations as follows :

1. Assignment operator: It is one of the simplest and widely used operator in c sharp, it is used to assign the legal value to the variables that are declared. It uses the equality symbol i.e “=”. In this expression the left operand is assigned to the right operand, and right operand has to be a variable. and right operand may be variable, immediate value or a sub expression.                                                                                                                                                         Example : uint roll_no = 1.
2. Arithmetic Operators: It contains operators that are used for doing arithmetic operations like addition, subtraction, multiplication and division using symbols like + , – ,* , /  respectively. It works on 2 operands and the resultant answer is stored using assignment operator. C# doesn’t produces fractional answers. Another operator known as modulo i.e % is used for returning remainder from division and not the quotient.                                                                                                                                                                       Example:     int a = 10;                                                                                                         int b = a/2;            //b=5                                                                                int b = a%2           //b=2                                                                                   int b = a*2            //b=20
3. Increment /Decrement Operators : It contains two operators that adds or subtracts 1 from the operand for Incrementing and decrementing respectively and result is stored back in the same operand. It uses ++ and – – keywords, and works with 1 operands. It may be used after the operand and known as postfix operator or before the operand which is known as prefix operator depending on the situation.                                                                                                                                                                                                                                                                                                                                                                                                                                   Example: int a = 10;                                                                                               int b =    a++                    //b=10 & a=11                                                      int b = ++a                    //b=11 & a=11                                       int b =    – -a                      //b= 9 & a = 9                                                 int b = a- –                      //b=10 & a =9
4. Relational Operator : These operators are used in loop and decision making statements for comparing values of its operands. The output after comparison is a boolean value i.e True or False.The operators and their description is given in the following table.
5.  Operator Description == Checks for equality if found equal return true or else return false != Checks  for non-equality, if found non equal then return true or else false > Compares value and if left hand side operand is greater then returns true or else false >= Compares value and if left hand side operand is greater or equal then returns true or else false < Compares value and if left hand side operand is less  then returns true or else false <= Compares value and if left hand side operand is less or equal then returns true or else false

Example :Int a = 10Int b= 20a<b                        //truea>b                        //false

6. Logical Operators : This operators are used for performing logical operations like AND, OR, NOT. The operators used are &&, ||. ! respectively. They are usually used when there are two conditions that need to be checked. Example of which will be given later post of decision making statements.

After studying about the operators and also about variables let us discuss about the classes and its objects
